     The shop manual shows a spec of between .004 and .025 for rocker arm end clearance. The .004 would seem to me a bit too tight and the .025 way too loose. What kind of clearance do you guys use that allows for heat expansion yets also makes for a fairly quiet top end? I have personally used up to .011 with roller rockers and seemed ok to these ears. Thanks, Bill
Anybody who tries to tell you that the press is the enemy of the people is just that.

my top end was really bad so i replaced the rockers,shafts and spacers
after assembly the intake spacing was at 8 and exhaust was 12 its the
quietest i have ever had for a shovel and that's with no shims

I'm with Pappy. We do 'em on a lathe at the shop and shoot for .008 to .010.
